I have decided to just create my own players for the 1949 Southern Association season using the Free Agents screen.
I know this will work well... I did it for my first two seasons of the SA replay and that stats were very realistic.
I have each player's real life batting, pitching and fielding stats.
It will just take time to manually create them and input their ratings... the pitching ratings will be difficult because of its complexity with stuff, movement, control and velocity... change one and everything else changes... but I will at least give it a try.
I was hoping to save a bunch of time with the minor league database player imports.
Maybe one day it will be possible to import entire teams and a specific league from the minors, complete with accurate stats and rosters.
And one day OOTPB will get there... It's a long, lengthy and time-demanding project.
